SSDNow E50

The SSDNow E50 is Kingston’s follow-up to the SSDNow E100 and like it, is also a SATA 3 6 GB/s solid state drive. Users can choose between 100 GB, 240 GB and 480 GB capacities with each capable of reaching a maximum sequential read speed of 550 MB/s and a maximum sequential write speed of 530 MB/s. The IOPS numbers reach 85,000 and 80,000 for 4k read and write respectively.

Running the show for the Kingston SSDNow E50 SSD is SandForce’s SF-2581 controller. In comparison, the earlier E10o runs on SF-2582, still from SandForce. The SF-2581 houses 19 nm MLC NAND modules while the SF-2582 utilizes 32 nm eMLC NAND. The difference in architecture is apparent when comparing the write endurance of the two SSDs. The 32 nm E100 has 2483 TBW and 11 DWPD while the 19 nm E50 has 739 TBW and 3 DWPD.

The SSDNow E50 has a Mean Time Between Failure (MTBF) of 1 million hours and a three-year warranty with technical support. As an “enterprise” drive, this SSD also comes with Reliability Tracking, Usage Statistics, Life Remaining, Wear Leveling, and Temperature indication tools.

Reviews:

With the release of the SSDNow E50, Kingston is now able to target the expanding entry-level enterprise market. This LSI SandForce driven SSD brings advanced firmware features and power-loss protection along for the ride.

When compared against some higher-priced enterprise drives, the E50 features a drastically reduced write lifespan. However, for a model which is meant to replace hard drives in those aforementioned read-heavy environments, we can easily overlook this.
